Home | Patients | Patient Cast Instructions

Patient Cast Instructions

A cast is worn to immobilise and support a fracture or injury, allowing the bone or tissue to heal in the proper position. It also helps to reduce pain and swelling and protects the injured area from further damage. We use various types of casts for different purposes, and the Plaster Nurse will confirm which cast you have been fitted with:

  • Soft Casts
  • Non-Fibreglass Casts
  • Fibreglass Casts
  • Plaster of Paris Casts

What is a Soft Cast?

A soft cast is made of a semi-rigid material that provides support for treating soft tissue injuries and fractures. It dries to the touch in 3-4 minutes and achieves full strength 30 minutes after application.

Patient Advice

  • Keep your limb elevated when not in use, especially in the early stages, to minimise swelling.
  • Exercise the joints that are not held in the cast as much as possible.

Cast Care

  • Please do not allow your cast to become wet (unless specifically permitted by your doctor) as it may cause skin problems or wound breakdown.
  • Please do not use any object to scratch the skin underneath your cast, as it can cause an ulcer to develop.
  • Do not cut, heat or remove your cast unless advised to do so by your Doctor/Nurse.

Removing a Soft Cast

Soft Casts are removed by unwinding or unravelling the cast as demonstrated by the plaster nurse.

When to contact a Doctor:

Contact your Doctor or the Plaster Department if you experience:

  • Pain that is not relieved by prescribed medication.
  • Colour changes (blue) or swelling of the toes or fingers, or difficulty in moving the limb.
  • Pins and needles or numbness.
  • A blister-like pain or rubbing under the cast.
  • Discharge, wetness or smell under the cast.
  • A loose, cracked or soft cast that is cause for concern.

Please also contact a doctor if you drop an object into the cast.

Non-fibreglass casts were developed to provide a greater degree of comfort and support. They are made from a combination of polyester and polypropylene. This cast combines the benefits of non-fibreglass materials with the strength and comfort associated with traditional fibreglass casts.

Patient Advice

  • Do not let the limb hang down unless it is being used. Keep your limb elevated when not in use, especially in the early stages, to minimise swelling.
  • Exercise the joints that are not held in the cast as much as possible.

Fibreglass casts have been developed for greater comfort and support. They consist of a knitted fibreglass fabric, fabricated and impregnated with polyurethane, a material that is lighter, stronger, and more water-resistant than traditional plaster casts.

Patient Advice

  • Do not let the limb hang down unless it is being used. Keep your limb elevated when not in use, especially in the early stages, to minimise swelling.
  • Exercise the joints that are not held in the cast as much as possible.

  • Please do not allow your cast to become wet (unless specifically permitted by your doctor) as it may cause skin problems or wound breakdown.
  • Please do not use any object to scratch the skin underneath your cast, as it can cause an ulcer to develop.
  • Do not cut, heat or remove your cast unless advised to do so by your Doctor/Nurse.

When to Contact A Doctor

Contact your Doctor or the Plaster Department if you experience:

  • Sudden, severe pain in the calf muscle (contact GP, Hospital or Emergency Department immediately)
  • Colour changes (blue) or swelling of the toes or fingers, or difficulty in moving the limb.
  • Pins and needles or numbness.
  • A blister-like pain or rubbing under the cast.
  • Discharge, wetness or smell under the cast.
  • The plaster cracks, softens, becomes loose or uncomfortable.

Please also contact a doctor if you drop an object into the cast.

Plaster of Paris can be easily shaped to fit the body’s contours, and skin irritation or allergies are quite rare.

Patient Advice

  • Exercise your fingers, toes, shoulder or elbow joints.
  • Elevate your plastered limb whenever possible.

Cast Care

  • Please do not stand ore press on your plaster for 48 hours.
  • Please do not use write on your plaster until it is dry.
  • Do not wet the plaster
  • Don’t cut, knock or bump the plaster
  • Please do not use any object to scratch the skin underneath your cast, as it can cause an ulcer to develop.

When to contact a Doctor:

Contact your Doctor or the Plaster Department if:

  • You cannot move your fingers or toes
  • You experience colour changes (blue) or swelling of the toes or fingers, or difficulty in moving the limb.
  • You are in severe pain
  • You experience pins and needles or numbness.
  • The plaster cracks, softens, becomes loose or uncomfortable.
